The present invention relates to phenanthroline compounds and to electroluminescent (EL) devices comprising the phenanthroline compounds. The phenanthroline compounds may function as electron transport layers, as hole blocking layers or as hosts for phosphorescent emitter materials to provide electroluminescent devices with improved efficiency, lifetime, operational stability and better spectral characteristics.
